Sorry for the late reply.
I would not call it unacceptable, just a bit unpleasant. We can merge it
if you cannot come up with a nicer way to do this. It was a good idea
to split to resend the series without this patch, but the replacement
to delete the aliases also doesn't look nice. If we can't come up with
a better way to do this, I'd suggest you re-send this patch and add a
bit more explanation into the changelog as to why you want this to
be done in an unusual way.
